5900x with 3080 PSU

[SaintPath]

Do I need 750w or 850w?

[AlwaysWong]

850w. Rtx 3080 is power hungry. 

[Letgomyleghoe]

 A solid 750w unit is fine for that pair.

He's right, best to get a 850W PSU.

ye, no, lol.

 

A good 750, or even a really good 650w unit is fine. you in no way need an 850w with that pair, speaking that even 9900k's drawing near 300w on some 650w psu's with an rtx 3080 where and are fine.

[Letgomyleghoe]

A good read OP. Use chrome and translate it. 750w is plenty.

Is 750 Watt 80 PLUS® Platinum Certified High Performance SFX PSU solid enough?

 

The reason I'm even considering and not going for 850 (because the price difference is really not high) is because I need SFX.
(if I'll change the case then I'll go 850)

yes the corsair sf750 will be fine, but honestly if you can get the 850w for like within $30 it would be better to go 850

But is there SFX with 850x?

Is there SFX with 850 by any chance?

Don't think so, not one worth buying anyway as they would have the same issues due to the size of the PSU.

oh I guess not, I've never looked at sfx psus before, lol, the corsair 750w will be fine

oh but yes it will, there was already testing with a 3080 and a 9900k drawing near 300w in which the corsair sfx 750w passed, i linked the article above.

some 650w psu's passed too.

Corsair tested them and all of them shut down with a 3080 and 3090.

 

That article is FOS.

Ask Jonny GURU, he did the testing and posted about it.

 

They can't handle the transient power spikes.

[SaintPath]

Ok, So I guess I would just go with the Lian-Li 011 Dynamic and not the Mini and that would solve my problem.

Thank you guys!

Yeah, that would be the smart thing to do.

 

It's just the SFX PSUs just don't have the room to put in the extra hardware to handle the power spikes.

 

They are like 976W from what he said, for 20ms... And he wasn't happy about it either.

Would it be enough for overlock? I'm considering to wait for the 3080ti and already have 5900X. Want to do some decent manual overclocking but can't decide 750W or 850W.

If you are going with a good tier A unit like an RM750x you should be fine, but I would go with 850 to play it safe.

Thank you very much. I'd like to have your advice regarding motherboard selection. Here is the post:
